Which of the following equations has a maximun? a. y=3x-1
b. y=4x^2+4
c. y=x^2
d. y=-7x^2-1

The answer is option D.

y = - 7x² - 1

It's maximum is ( 0 , - 1)

Hope this helps you

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
